HDMI and DisplayPort connections have different EDIDs. Are you looking at the DisplayPort EDID or the HDMI EDID (they might have different product IDs)?

CRU only shows 3 extension blocks. If the detailed timing was on a fourth then it could be missing (usually 3 is enough so I doubt this is the problem). Double-check the EDIDs in Monitor Asset Manager (moninfo.exe).

The display is not using a standard timing because it won't fit in the allowed range 330 MHz max (CRU should probably rename the timings to GTF, CVT, CVT-RB, CVT-RB2 so we know what standard is being used - 1920x1080 144Hz 346 MHz is CVT-RB).

If the EDID comes with a 144 Hz timing using 325 MHz, then why are you creating another timing using 346 MHz?
